Vista 3D cube theme??? Beryl vs. Gnome? - 3d cube game sohu

So, I know it is the subject of a 3D cube thingy majiger for Vista, and I will receive. But I do not want third, I want the real deal. I have Beryl & & Gnome and heard, but what is better? or another is better? In addition, it slows down the computer? I have an XPS M1330 and I saw Umm information system and virtual memory, a total of 7.17,,, soo i dont know? but I do not want to eat slowly, the problem to the computer, I do not have the computer for games, to all school work, photos, and installed some videos & & im going this thing, and I Dragon has heard a lot of memory.
